章 744: Chapter 718: The Atmosphere Falls into an Awkwardly Sweet Situation (Thanks to Xuanyuan Yuchen and Shi Bi for the update)

Yellow Hair thought his security was flawless, but Yu Minglang sensed something strange from it.

In China, the leaf lock is mostly used in safes, which is not very unusual. However, what was unusual was the internal structure of this lock.

This leaf lock seemed to have been made with a special technology, and the internal structure was extremely precise. It seemed to have been custom-made, which made him even more suspicious of Yellow Hair's background. He couldn't help but think of the brass knuckles he took from Old Mai's hand.

Both were high-tech, could these two people be related?

As he was thinking, the elevator came up, and Yu Minglang quickly moved to the side, picked up his breakfast, and knocked on his door.

While waiting for the door to open, the elevator opened, and a young man came in with a large bouquet of roses. He took out a paper note, checked the door number to make sure it was right.
